Not every PowerPoint slide is meant for presentations to a big audience. Some charts are meant for pondering behind a big screen. The one below is an example (made by FirstMark Capital).
Venture capitalists love these industry overviews full of logos and sectors. You could make this chart cleaner:
- Replace logos with small text boxes
- Perfectly line up all these tiny text boxes in a grid
- Replace the rounded-corner shapes with shaded rectangles without a framing line
But that chart would be less fund to ponder....
